This needs to be diluted through printing - the only way to get it out from under the mattress is to print and spend till they have no bloody choice.
Then the cash horde earns more interest to keep up with ensuing inflation opebo, or the corps switch to another currency. Try again.
Come on buddy, you know if the State printed and spent they would create such economic growth that the corporations would have incentive to invest. Of course my personal preference would involve the guillotine for all involved in such crimes as this, but that's probably too much to hope for.
Even if the cash supply exceeds the country's GDP?
Cash and GDP are not comparable concepts. One is a flow variable and the other is a stock variable.
